TDM Pulse Amplitude Modulation & Demodulation

Product Description

ME  777- TDMPulse  Amplitude Modulation &Demodulation

Objective :Pulse amplitude modulation technique & Time division multiplexing and demultiplexing

PLL as frequency multiplier to generate clock from sync signal

•  connection(information only) clock and sync derived at receiver
•  connections(information sync) clock regenerated at receiver
•  connection between transmitter & receiver (clock, sync & information)

Effect of vary ingduty cycle of sampling pulse on signal reconstruction
